Personally, I use PotPlayer 64Bit but, Media Player Classic is probably the most user friendly media player on the planet. PotPlayer lets me customise - add different skins and toolbars etc which is why I use it. Media Player Classic is very lightweight, open source, plays everything. It does out perform VLC, we ran a test on a private site early this year, MPC just beat VLC - VLC struggled to play some formats, Transport Stream for instance, MPC played everything flawlessly.
